San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

What Are The Best Baits To Use To Trap A Rat?
If you have the right kind of bait in place, trapping rats becomes relatively easy. These animals are naturally curious and become fearless when they see eye-catching foods. To remove them from your home, all you have to do is take advantage of this and trap as many rats as you can.
Are you looking for the best bait ideas that will help you trap all the rats in your house? Right here, we will be sharing some for you. But first, there is a particular thing you need to put in place if you want this to be effective. The first thing you need to do is to seal up every possible entry hole into your house to prevent more rats from gaining entrance. Once that is done, you can then go ahead to trap the rats in your house.
When it comes to rat baits, peanut butter is one of the best. This particular bait attracts rats more than any other type of bait. Apart from having a strong smell, it is easy to set on traps that you intend to use to capture the rats.
Other types of baits include pineapple, chocolate, bacon, whole nuts, berries, dried fruit, gumdrops, and many more. Each of these baits will help you to achieve exactly what you want without putting you through the stress of having to replace them over and over again just to help attract rats.
Having realized this, all you have to do is get one of these baits and place it on the trap in a manner that the rats passing will be able to see it and will want to have it.
